Actually, it is equivalent to $0.015. The faucet claim amount fluctuates for the price change of Bitcoin, but it remains equivalent to $0.015 in crypto always. And the gap between two faucet claim is indeed 1 minute. I just checked it by claiming faucets on my account. Seems like you have followed the wrong details
I received exactly 0.00000078 BTC yesterday when I tested the faucet just like they mentioned it in their rules. I haven't tested the cooldown period because this amount isn't enough to make a bet apparently. When I try to bet it on their dice game, I am getting a
balance too low error. If I try to claim the faucet a 2nd time, I am informed that I can't because I already have 0.00000078 BTC on my account. Seems that the amounts you receive can't be used for anything, which defeats the purpose of having a faucet in the first place. I will contact their support and try to find out more information about the amounts and the cooldown period between claims.
Probably the faucet claim is disabled there as they have confirmed it to you through email.
I removed Simpledice from the OP.
